Does anyone have a comprehensive list of games for windows that have achievements, my gamerscores been pretty stagnant really and i wanna get some good PC games
Haha well here's a list of all the Games for Windows titles, presumably all those with the Live green tick will have achievements. http://en.wikipedia.org/wiki/List_of_Games_for_Windows_titles
This website focuses on 360 games, but they also include PC titles since the Live account is shared: http://www.xbox360achievements.org/games/PC/
Plus most of those games have a separate list to the 360 version, so you could have GTAIV 360 and GTAIV PC on your list for up to 2000 points.
Same with Fallout 3. There's my gamer card. Used to play 360 loads before I could afford a decent PC.
